What factors affect concrete slab pricing?

How much are concrete slabs and what affects the total cost? The price of concrete slab is affected by a range of factors. These include:

• Size and thickness of the slab: A thicker slab uses more concrete and increases labour costs
• Type of concrete you choose.
• Ease of access to the site: A flat block is easier and quicker to work with than a sloping block, which will cost more per square metre.
• Length of time it takes to complete the job: A larger, more complicated project will take more time to set up and execute, and more labour hours, which means a bigger quote.
• Your location: If you live far away from the concrete contractors, or if the market rates are higher in your area, you might receive a higher quote.

In Australia, if you’re using an online concrete slab cost calculator, you might receive estimates within a “from” price, which will only give you a slight indication of the overall cost of installation. The best way to get an accurate cost of concrete slab installation is to ask for quotes from local concrete contractors.
